Several people are using humidity sensors very successfully with SmartThings.

@jody.albritton uses them I think to turn on a humidifier.

@rayzurbock has an app that turns off the bathroom light when there’s a period of no motion in the bathroom, BUT extends that time when the humidity level is rising, on the assumption there’s someone in the shower.

Very clever. Not for me, since my first question is always “Will the lights be on after a fall?” But, hey, “your use case is not my use case.”

Anyway, he has a lot of experience with ST and humidity detection during showers.

[OBSOLETE] Bathroom Light Control

Bathroom Light Control Initial Release: 1.0.1 Controls bathroom lights: Turn on light when motion is detected. Turn off light after x minutes of no motion detection Extend light off timer to x minutes if humidity sensor is above the average for the room and trending upward (shower in use?) Developed / Tested with Aeon Multisensor which by default sends humidity every 8 minutes. We need to detect that humidity is rising with 1 reading as most people will want this to kick in by the 8 minute period and not 2 polls which would be 16 minutes. To do so we calculate the average temp over a period of readings (4 by default), then if the humidity is higher than the average and higher than the last reading, it is determined that humidity level is trending upward, so we adjust the off timer to…
